Title: Process for the manufacture of water-insoluble azodyestuffs on cellulosic fibres
IPC: C09B67/36
Filed: 1935-02-14
Abstract: Water-insoluble azo-dyes are prepared on cellulosic fibres by applying the coupling component to the fibre in an undissolved finely divided form and developing by treatment with a diazo solution.  The dispersion of coupling component is effected in known manner for instance by suspension in water containing a dispersing agent or protective colloid followed or not by evaporating to dryness; suitable agents are sulphite waste liquor and its condensation products with organic bases, condensation products of formaldehyde and naphthalene sulphonic acids, alkali metal salts of isobutyl- or propylnaphthalene sulphonic acids, acid amides, esters and ethers of higher molecular saturated or unsaturated or hydroxy fatty acids, and ethers and esters of higher molecular fatty alcohols and their sulphonation products. The finely divided component is worked into a slop-padding liquor and the material impregnated in this is developed, if desired after passing through an alkaline bath such as dilute caustic soda or ammonia and drying.  In examples: (1) 1-(2<1>.3<1>-oxynaphthoylamino)-3.4.5.-trichlorbenzene is pasted with a formaldehyde-b -naphthalenesulphonic acid condensation product and evaporated to dryness; this preparation is stirred with water containing turkey red oil or triethanolamine and cotton impregnated therein is passed through a bath of dilute caustic soda prior to development with diazotized 2.5-dichloraniline; (2) 1-(2<1>.3<1> - oxynaphthoylamino) - 2.4 - dimethoxy-5-chlorbenzene is pasted with oleylmethyltaurine and ground prior to making up with water; a mixed cotton-viscose silk fabric is slop-padded in this and developed in a solution of diazotized 1-methoxy-2-amino-benzene-4-sulphonic acid diethylamide; the fabric may be passed through a dilute caustic soda bath prior to development.

Title: Apparatus for measuring the thickness of tubes, plates or the like, particularly at points situated at comparatively great distances from the ends or edges of the articles
Filed: 1944-03-15
Abstract: 576,956. Thickness gauges. SEE FABRIKS AKTIEBOLAG. March 15, 1944, No. 4848. Convention date, Feb. 12, 1943. [Class 106 (ii)] Apparatus for measuring, the thickness of material at points difficult of access, for example at different points of a tube or plate, comprises feeling members located opposite to one another by a firmly stretched wire or rod subjected to tension, the arrangement of the supports &c. being such as to permit relative movement between the article and the feeling members. The adjustment of the feelers may be effected automatically. When the point of measurement is touched by both feelers, an electric circuit may be closed to give a sound or light signal and to operate a device for locking the measuring-instrument. Fig. 1 shows a tube a located for thickness tests between a feeler and secured to a stretched wire or rod 4 on a frame 1, and a feeler 7 guided in the frame 1 so as to operate by its displacement an indicator 8, contact across the tube a serving to complete a circuit for a light signal 13. In a modification, Fig. 3, the feelers 17 are pivoted to clamps 16 on two parallel wires subjected to tension by hydraulically operated pistons. Sleeves 18 slidable on the wires 4 are displaced by the feelers to actuate an indicator 20. A duplicate outfit may be provided where the tube is long. Continuous recording-instruments of known type may be incorporated. Either the wires or the tube may be arranged to be movable. Alternatively, both wires and tube may be stationary, and the clamps 16 mounted so as to be slidable along the wires 4, the members 16 and the indicator 20 being connected to wires slidable in grooves in the wires 4. Tubes of great length may 'be supported on a series of holders 46, Figs. 9 and 10, adapted to be independently adjustable in height by set-screws 41 positioning about a shaft 39 pivoted arms 40 which engage sliding pins 44 guided in heads 45 on arms 38. An adjustable counterweight 49 is set so that the tube a rests with slight pressure only against the feeler contact 34 on the steel wire 33. The inter-connected carriages 36 for the tube supports 46 have rollers 35 running on parallel rods 32. Under the tube a opposite the stationary feeler contact 34 is a second contact adjusted by a micrometer screw 55, 56, serving as the measuring instrument, an electromagnet 57 locking the micrometer on closure of the circuit. When the tube is not an electric conductor, adjustment of the micrometer may cause the tube to close a switch 64 connecting wires 33, 60, Figs. 12 and 13.

Filed: 1939-02-14
Abstract: 525,084. Electric control systems. NEHRKE, C. Feb. 14, 1939, No. 4873. Convention date, Aug. 23, 1938. [Class 40 (i)] [Also in Groups XXXVI and XL] A push-button, tuning system for a radio receiver comprises at least one moving band 28, 29 of conducting material, each separated into two portions 28A, 28B, insulated from each other by an insulator and tension spring 30C and an insulating slide member 30 which provides a slot 31, 32 in each band, breaking the continuity thereof. The bands rotate over metal pulleys 30A, 30B and are operated by an endless cord 47, secured to the insulating slider 30 at 46, and actuated by a driving pulley 50 coupled to the driving motor 37. Each insulated half-portion of the bands 28, 29 is connected over the pulleys 30A, 30B to one terminal of the A.C. motor 37, the third terminal of which is connected to a bus-bar 12 over a transformer secondary 40. In the front plate 9 of the set there are two lateral slots 14, 15 corresponding to and co-extensive with the front portions of the bands 28, 29. In these slots contact members 16 are adjustably positioned by springs 20, 24 as shown in Fig. 6, the members 17 having metallic heads 23 engaging the bands 28, 29 while connections 25 are also taken from each member 16 to one side of each of a corresponding number of switch contacts 26, 27 operated by push-buttons 2 ... 5, Fig. 8, shown as bell-crank levers 6 in Fig. 6. Depression of any button closes a contact 27 and energizes one winding of the motor 37 through the bands 28 or 29, which then drives the timing element and moves the bands through the system 58, 48, 49, 47, 46 until the slot 31 or 32 comes under the contact 23 when the tuning is arrested at the desired station. The member 30 carries a pointer 63 cooperating with an indicating scale for manual tuning which may be effected by a knob 68, Fig. 10, slight rotation of which in either direction closes the motor circuit for right- or left-hand running of the motor. The knob 66 actuates the tuning spindle directly and is used for fine tuning. Silent tuning is effected by contacts operated by the motor armature when the latter is switched in. Reference has been directed by the Comptroller to Specification 494,026.
Patent GB-455191-A (GB)
Title: Improvements relating to remote controls for marine power plants
IPC: B63H21/22
Filed: 1936-02-18
Abstract: 455,191. Controlling reversing-gear for boats. HARRISON, H. G., Onwards, Sycamore Road, Farnborough, Hampshire. Feb. 18, 1936, No. 4901. Addition to 429,213. [Class 114] [See also Group XXIV] Relates to remote controls for marine internal-combustion power plant wherein a deck telegraph operates both the engine throttle or other fuel control and a servomotor operating the reverse gear lever. The engine is prevented from being speeded up while not under load by obstructing pawls 6, Figs. 2 and 3, which are operated positively in both directions from the servomotor 19. The telegraph, not shown, works through a chain 16 upon a drum 9 which operates a distributer valve 17, Fig. 1, for controlling the motor 19 to throw its piston-rod 3 one way or the other. The drum 9 has a crank connection 12 with a throttle rod 11 which is in dead centre in the neutral position of the valve drum 9 shown in Fig. 2. When the telegraph is turned, say, towards the "ahead" position, the valve drum 9 turns through about 25‹ and is then stopped by a peg 10, which it carries, engaging one of a pair of pawls 6 carried by a three-armed rocking lever 1. This displacement of the drum 9 suffices to energize the servomotor 19 so that the piston 3 shoots to the end of its stroke, completing the change in the gear-box, and, through a linkage 4, 5, 2, Fig. 1, rocking the lever 1 to the position shown in Fig. 3. The operative obstructing pawl 6 has thus been moved out of the path of the peg 10, so that the drum 9 is free to be turned farther counter-clockwise by the deck telegraph so as to displace the rod 11 left to speed up the engine. When the telegraph is turned the other way, the peg 10 is stopped by the other pawl 6 until the end of the piston stroke, which ensures that the gear change in the mechanical gearbox has been completed, upon which the drum 9 is freed, as before, and the throttle rod 11 is displaced left, as before. The servomotor 19 may be vacuum, compressed air, or hydraulic. It is sometimes desired to speed up the engine when the vessel is not under way, as when the engine is geared to a winch. To this end, the lever 1 is rocked with the piston. 3 in neutral by changing the length of the link 2 by moving a bolt 13 out of a lock notch 14, Fig. 2, and into a lock notch 15. An auxiliary slide-valve chest 18 is for centring the piston 3 in neutral. Specification 400,438 is referred to.
